How to get bed bugs out of wallpaper? - briefly
Detach the wallpaper and apply a high‑temperature steam treatment or a certified bed‑bug insecticide to the exposed wall surface. Follow with thorough vacuuming of seams and sealing of cracks to prevent re‑infestation.
How to get bed bugs out of wallpaper? - in detail
Eliminating bed‑bug infestations from wall coverings requires a systematic approach that combines mechanical removal, chemical treatment, and preventive measures.
Physical extraction begins with a thorough inspection. Use a bright light and a magnifying lens to locate live insects, eggs, and shed skins on the surface and in seams. Gently scrape the wallpaper with a stiff‑bristled brush or a disposable putty knife, transferring debris onto a white disposable sheet for visual confirmation. Collect all material in a sealed plastic bag for disposal.
Chemical control follows the mechanical stage. Apply a residual insecticide labeled for indoor use on porous surfaces, ensuring coverage of the entire wallpaper area. Spray in thin, even layers, avoiding oversaturation that could damage the paper. Allow the product to dry according to the manufacturer’s instructions before re‑entering the room.
Heat treatment serves as an additional non‑chemical option. Raise the ambient temperature of the affected wall to at least 45 °C (113 °F) for a minimum of 30 minutes, using portable infrared heaters positioned at a safe distance. Monitor temperature with a calibrated thermometer to maintain consistent exposure.
After treatment, seal the environment to prevent re‑infestation:
- Install airtight covers over wall cracks and gaps.
- Reduce clutter that can harbor insects.
- Maintain regular vacuuming with a HEPA‑filter unit, focusing on wallpaper edges.
- Schedule periodic inspections to detect early signs of resurgence.
If damage to the wallpaper is extensive, replace the affected sections after confirming the absence of live insects. Use new, treated wall covering material and apply a barrier primer before installation to inhibit future penetration.
